Same-day response, 09:30 AM actually, to our clogged waste line. They snaked it and got us flowing again fast. Very reasonably priced. Nice guys too. This was the second time that we've used them. (We have a drain line trouble spot.) Will use again. read more

Months after Hugo took care of my hot water heater I was having fun with a Sawz-all on some sprinkler pipes while digging a hole for a tree....hit the sprinkler main, a fountain sprang forth and I thought I made an expensive mistake.... Hugo promptly called me back and told me how to fix it, it's simple.....just an example of how customer-service minded he is read more

Use them at our properties. Over 5 year relationship with Diamond Plumbing. They are so fast to respond and professional. Hugo is very knowledgeable and loves what he does. Our tenants say great things about them as well. read more

I can't recommend them enough. They are always responsive, even late at night, and will try to help you over text first so you don't have to pay for a visit if it's something you can fix yourself. That alone says a lot. They're incredibly honest and will actually tell you not to do something if it's a waste of money. They explain what's truly fixable, how much life something realistically has left, and when a replacement actually makes sense -- no pressure, no upsell. What really stands out is the care. They'll check in on you even if you end up using another company because of home insurance. Excellent customer service is an understatement -- they build real, long-term relationships. I've been with them for over a decade, and I trust them completely. If you want someone who's knowledgeable, responsive, and genuinely looking out for you, this is your plumber. read more

Our water heater burst over the weekend and Diamond Plumbing was able to quickly (which is appreciated) send someone over to assess the damage; doing a complete replacement day of. Hugo was very communicative over the phone throughout the entire process and fast to respond as well as very informative on what our options were. He and Angel were both pleasant to work with and are meticulous people who wanted to make sure the job was done right before actually calling it complete. Overall, it was a great experience and I highly recommend them. I was originally going to go with a franchise plumber, but saw the bad reviews for those companies- so I'm glad I went with Diamond! read more

I've been putting off having a plumber come out to fix my drains. I wanted to say I had a great experience with Hugo. 1st he was prompt and came out same day. I wasn't in a rush but this really helped. He ran a camera to show me the plug had worked itself out BUT I had several other small issues he was equipped to handle for. He explained everything to me & made recommendations for work I should do & even showed me a newer way to do this. If I have plumbing issues again I will definitely give them a call. Rates are on par with other companies. They are licensed & insured I found them via YELP when I posted a "project" I appreciate the help! It's nice to have 2 working bathrooms again. read more

Super fair, prompt and easy to work with. They'll break down what needs to be done and won't push you for the most expensive option. I've used them several times over the last few years and it's always been good working with Hugo and the team. read more

Professional, prompt, and friendly service! I woke up this morning and learned my earthquake gas shut off valve was on the fritz. I called Diamond Plumbing and Alfonso was on site and fixed the problem within a couple hours. He even helped me relight the pilot for my water heater. Highly recommend you give Diamond Plumbing a call for your plumbing needs!! read more

I had my kitchen sink clogged for 3 days. On Sunday I called Roto-Rooter, what a shitty service and a thief (charge $500 and they didn't even unclogged it)... DON'T EVER call Roto-Rooter... After they try to get more money, additional $700 bucks to come back the next day to try to fix it, I do research that night. Bam, I found Diamond Plumbing and Rooter.. Alfonso came the next morning. Wow, what a service.. He took care of the clogged where Roto-Rooter could not and only cost 60% of what Roto-Rooter charged.. Alfonso had a hard time trying to get it unclogged but he never gave up. After 3 tries, he got it unclogged.. He also explain in detail what he did and what expectation to have, the whole 9 yards.. Wow what a service.. Diamond Plumbing match the service they give. On top of the the price is way cheaper then the other plumber like 50% cheaper.. Thank you Diamond Plumber.. highly recommended read more

Everything was handled professionally, from providing a competitive market price to taking care of the work with quality. My house has a leak, and need to replace the drain line. Hugo and his team respond right away, even though it is a crawl space situation. The whole process runs smoothly, and now we have reliable plumbing system. Even my 4 cats would appreciate that there ain't too much noise or excessive grounding all 4 of them in my bedroom for long hours. Glad to finally find a reliable plumber around the neighborhood. read more

Hugo is extremely communicative, thorough, and prompt. We called him for a leak in our washing machine drain, and he came right over, identified the problem, sent us a quote almost immediately, scheduled the repair the same week, and had the job complete in one day. I wouldn't trust anyone else for any plumbing repairs in the future - his price was fair, and he was very professional! read more

I had a problem with my shower with very little pressure. I called Roto-Rooter and they gave an outragious price, so i declined. Then i did research with different plumbers in the area and saw that Diamond Plumbing had great reviews so i called and got an immediate response and a price quote over the phone. Within an hour Alphonso showed up and i already knew this was going to be a pleasant experience. Alphonso went above and beyond to fix the problem, very technical with alot of integrity which is very hard to find nowadays. Give that man a big raise. I found my new plumbing contractor. You guys rock. Thanks again :) read more

Good work on replacing drain with to many tight turns to less turns and gentler angles. Add Y, straight shot clean out, snake and line cleared better than ever in 10 years Received recommendations for additional repairs that was aware of, but declined. Kept bringing up. Go easy on the sales push and will get more call backs for new service. read more

I had a clog from the clean out to the street. I called Diamond Plumbing and they were able to send someone within an hour. Angel arrived and cleared the problem post haste. He was professional, and took the time to explain the problem to me. While he was here, I asked him if he could fix the toilet in the back and he was able to diagnose the issue and complete that repair as well. I am grateful for their expertise and quick response time. read more

TLDR: good price, excellent work, highly recommended We had Diamond out to snake out our kitchen drain after something got stuck pretty far down and I couldn't get it unclogged with my own 25' snake. First off I want to say, the only plumber I called that would even remotely give me a quote on possible services over the phone. We chatted for a second, he gave me a few basic prices based on what it could be and what would be the first step to take and if it escalated from there. Awesome. Information I need, not any of this " we will send a person who will quote everything there". They sent Angel who was awesome. Angel ways super nice, super knowledgeable and exactly they type of person I want sent to solve my problem. 120% exactly the company I wanted and will call again in the future. read more

Very professional, responsive, willing to negotiate price, and on time. Their work was excellent- my husband usually does our plumbing, but is injured, and was really impressed. These fellows are really nice, too!!!! read more

Needed plumbing services again and was just happy I was able to find my number for Diamond Plumbing again. Called in the morning, Hugo answered; gave me a same day window of 1-3, called me when enroute and showed up promptly around 2. He and Alfonso were communicative, respectful, professional, polite. Stand-up guys with integrity...which is not easy to find. They helped me locate my water valve which is located in a neighbor's front yard (I live in a condo complex) 3 houses down so it was not intuitive. Alfonso replaced a plastic valve with a steel one with its own shut off valve so I don't have to worry about going in my neighbors yard again. They were in and out promptly, same day, affordably fair priced. I will always go to Hugo and Alfonso at Diamond Plumbing and highly recommend them. read more

I called Diamond Plumbing & Rooter to fix a leakage coming from my dishwasher. Miguel was sincere and thorough on what needed to be fixed. He did a fantastic job at a reasonable price. Highly recommended this business for your plumbing needs. Thanks Miguel! read more

Marge: This company is absolutely awesome. I had a problem with the bathroom sink stopper, and the rod down into the drain. Hugo came out within 30 minutes, took a look at it and was able to fix an or repair the rod and reattaching it to the pop-up stopper. So so relieved. Hugo is awesome. He is polite, professional, and really knows his stuff. He cares about your situation no matter if it's big or small. He's the guy you call. I will not hesitate to call on him again or refer him to friends or family. The price was beyond my expectations as far as reasonable. Very honest company. Everybody wants a company that they can trust and is fair and this is that company. Don't hesitate to call Hugo at Diamond Plumbing. read more

I encountered an issue with my bathtub faucet after hours and sent a message. I received an immediate response, and they arrived first thing this morning. A big thank you to Hugo and Angel for their prompt service and resolving the problem. I'll definitely be turning to Diamond Plumbing & Rooter for any future needs. read more

We've used Diamond Plumbing several times over the years for both big projects and small fixes. They have always been professional, honest and friendly. I cannot recommend them highly enough. read more

Hugo is amazing man! He is the most respectful, knowledgeable and honest plumber I have ever meet! He will always be there for any needed and he is very respond fast! Thank you! read more

I've had sewer lateral blockage problem every 1-4 years for the last many years and called out different plumbers to clear the blockage, and they were good. I tried Diamond this time, and Alfonso was great! He was extremely professional, explained everything he did along the way, and in words that a homeowner (me) can understand. He cleared the blockage and ran the snake 100 feet to clear anything else that may have been further down the pipe. Diamond was also quick to respond...I called them around 3:30 pm and Alfonso left at 5:40. Awesome service! read more

Had a clog in the kitchen. They responded within the hour and resolved the issue. The plumber who came out explained exactly what the issue was and how to prevent it in the future. Not sure how the price compares but it seemed reasonable given it was an urgent call. read more

Highly highly recommend Diamond plumbing! At 11pm on a weeknight our newly installed showerhead sprung a leak and was dripping through a recessed light downstairs. I frantically messaged them on Yelp and the owner answered and said they'd have someone at our house the next morning. When the technician arrived he took a look at our showerhead, immediately diagnosed the problem, quoted it, and fixed it within the hour. Didn't overcharge us at all and our recessed light no longer leaks! read more

I called Diamond plumbing to inspect a sewer smell coming from our front bathroom. Hugo was able to send someone that day and they discovered a water leak under the house. The water had to be remediated before they could identify the source of the leak. Hugo recommended ARC water damage and coordinated with them to contact me. Once the water was cleaned up, Hugo had his crew back out the same day. They identified the leak and presented me with a few options to repair the damage. The next day the crew performed the work, and we were back in business. They were responsive, clean, efficient, and priced fairly. Thanks Hugo and crew! If we need plumbing service in the future you will be our first call. read more

Diamond plumbers are amongst the most capable and knowledgeable I have used. Hugo's team are experts in dealing with any plumbing issue and explain to you and show you survey pics of the problem and the solution as a fix. They do not baffle you or try to make what it is seem complicated. you know what your paying for to have fixed before they carry out the fix. Our broken pipe was undetectable but Diamond proved right diagnosis and to fix and improve so it will not happen again. Excellent team very capable they will be my preferred plumbing fix. read more

It is such a good feeling when you find a plumber that is not only reliable and punctual, but also honest and trustworthy! I am a testament that the running positive reviews and 5 star ratings you see on their page is not a fluke! I called Hugo when my husband and I thought there was a leak under our house. He was thorough in his inspection, great at explaining some of the underground workings of our pipes, and ultimately made sure we didn't pay for anything we didn't need. There are plenty of times when you know exactly what you need (he's probably great at that too), but if you don't, this is the place for you. We will be coming back to Hugo any and all future plumbing needs. read more

We had a problem with flushing system in a non-standard toilet. Required device that we bought somehow did not work. A plumber from another company said that they do not have the needed element (prices of those elements are less than $15) and that we should buy a new toilet :=). The environment actually required not only toilet replacement, but full bathroom remodeling. Called Diamond Plumbers (thanks to Yelp). Alfonso came at scheduled hour and agreed that the case is complicated. He measured the elements of the system and left for an hour. Returned with several pieces, one of which after some work fit the flushing system. Of course the price was higher than usual, but we are happy we do not need bathroom remodeling. Alfonso gave us a discount and added a month warranty. It works well and we are happy we called Diamond. read more

Miguel came by and assessed our leaked pipe / clogged pipe situation. Told us the pricing up front and told us all the options we had. He didn't have to do this but chose to anyways. He said we could go through our home warranty or call our remodeling contractors; either option would potentially save me hundreds of dollars, which we ended up doing. But he could have just said he can fix and we would have happily paid him to do it. What he did though really helped us out, and there's no way in hell we are going to ever reach out to anyone else about home plumbing issues in the future. They've won us over and we are so glad we found the family business to go to now! Miguel also likes to give you tips and tricks on home plumbing. He is passionate about his work. Be prepared to learn! read more

They are wonderful! I have used them twice and they are prompt. The latest is when they came and it was raining heavily and they confirmed that my sink didn't need repair and didn't charge me! Definitely use them as your plumber! read more

Fast service, fast workers. I am so thankful I found this company. Their prices are very reasonable. They do fantastic work quick. They showed up quickly and got the job done. Took their time to explain everything so we knew exactly what was happening. They do fantastic work. They installed a 2 way clean out, snaked my entire line to make sure it was clear and put a camera in my line to make sure the rest of the pipes were good and no other problems anywhere. These guys are amazing. All work was done withing a couple hours. I just dont know what to say except, THANK YOU! I highly recommend Diamond Plumbing & Rooter read more
